Question about Sharp AR-M277 All-In-One Printer
I have cleaned all glass surfaces thoroughly and I still get black lines whether I use the document feeder or the scaner bed. help Don johnson.
Common to have deris on the charge corona that is located inside the drum unit. If you take the toner out and remove the one blue screw, the developer unit will pull out (be careful not to spill as the top is open on the developer unit). Make sure the right side door is open and then you can pull the drum unit out.
Check first if there is the line of toner still on the drum where it would match the lines on the paper. If so.... the drum cleaning blade is the culprit. If not, then you would need to remove two screws that hold the main charge unit in place and remove and clean it very thouroughly with canned air. Even small lint or hair can cause fuzzy looking lines.
The maintenance cycle on the developer and drums it 75,000. If you are in that range, it is ready for a PM anyway and the drum cartridge should be completely rebuilt with new parts.
What I described may buy you some time is all.
